L LAMP-BURNER' CONNECTER.

Application med uoctober 2e, 1925'. serial No. casse.

The invention relates to improvements in oil lamps and has reference todevices which are intended to prevent total accidental disconnection ofthe burner from thelamp bowl andpmovement of the wick from lsuch bowl,when the burner is unscre'wed for filling the lamp.

The object of an extremely simple and inexpensive device of thischaracter, yet one "which will be etticient and desirable, theconstruction being such that the device may readily be released byfinger pressure when the burner is to be entirely disconnected from thelamp bowl, and finger-engaged releasing portions of such device are soconstructed and ar# ranged, that they slidably engage edges of the usualwick, to prevent movement of such wick out of the filling neck of thebowl when the burner isunscrewed, ceven though said wick be rathershort.

With the foregoing in view, the invention resides in thenovel'subjectmatter hereinafter described and claimed, the descriptionbeing supplemented by 'the accompanying drawing.

Figure 1 is a vertical sectional view partly inelevation showing myinvention. Figure 2 is a view similar to Fig. 1 but looking in adifferent direction.

Figure 3 is a perspective view of the im- ,proved connecter.

In th drawing above brie-Hy described, B designates the bowl of an oillamp, said bowl having the usual wick-receiving and filling neck eNJ,into which the burner b is threaded, the wick of said burner being`designated at W. f

- The improved connecter is formed from a.

single piece of spring Wire bent at its center to forma coil 4 and arms5 which project downwardly from such coil, the lower ends of these armsbeing bent late/rally outward to provide stops 6 which engage `the upperend of the bowl when the burner b is uny threaded from the neck N andmoved to the -side for filling the bow1said stops thereby preventingtotal accidental disconnection of the burnerfrom the bowl and preventingmovement of the wick out of the neck. The

l arms 5 have the lower'portions 7 ofrtheir lengths, offset from theupper portions thereof, so that said upper portions may be dis-K posedat one side of the wick and the lower portions 7 at the opposite sidethereof, these upper and lower portions being connected by the inventionis to provide `V with the portions 8 of the arms 5, it cannot moveentirely out of the neck N, when the burner is disconnected from thebowl and moved aside. By grlppingthe two portions 8, however, betweenthe thumb and fore-r nger, the arms 5 may be pressed inwardly as shownindotted lines in Fig. 1, thuspermitting the stops 6y to pass through theneck N when it is desired to entirely disconnect the burner from thebowl.

It will be seen from the foregoing that the .improved connecter isexceptionally simple and inexpensive, yet is leiiicient and desirableand may be used on all Hat wick burners.' It

will also be seen that the particular improvement upon 'which patentprotection is sought,

is the formation at the intermediate portions? of the arms-5, providinglinger pieces Vand wick retainers. Obviously the upper Yend of theconnecter may be attac ed to the burner by any preferred means, such asthe wire link indica-ted at 9, and while it is preferable ltofform .aneye 4 at the upper end of the de- -vice, this exact formation is not inall instances required.

We claim: a 1. In a means forypreventing totalY accidental disconnectionof a lamp burner from the neck of the lamp bowl, a single-length ofspring wire bent substantially upon itself at its center to form twoarms adapted upper ends of said arms being connected with each other andhaving loose connection with the burner, the lower ends of the armsVbeing Abent laterally outward to form stops which prevent totalwithdrawal of said arms from the neck until forced inwardly to permitthe stops to clear said neck, the inte-r4 mediateportions of said armshaving out- Jwardly bent finger pieces by means of which said arms maybe inwardly forced to the required extent, the upper-and lower portionsof said arms being oit-.set forv disposition at opposite sides of thelamp wick, said finger to extend through the neck of the bowl, the Y i ipieces being of- U-shape, connecting said upof spring wire bentsubstantially upon it self at `,its center to form two arms adapted toextend through the neck ofthe bowl, the upper ends of said arms beingconnected with each other and having` loose connection with. the burner,the lower ends of the arms beingr bent laterally outward to form stopswhich prevent total withdrawal of said arms from the neck until forcedinwardly to perm .mit the stops to cleaisaid neck, the interlmediateportions of saidI arms' being outf wadly bentinto U-shape formto providefinger pieces .which project toward the edges of the wick and serve asmeans for inwardly forcing'said larms to positions at which theaforesaid stopswill clear` the neck.

In testimony whereof we have hereunto'
